Echocardiography: The test is also called echocardiography or diagnostic cardiac ultrasound. Quick facts. An echo uses sound waves to create pictures of your heart’s chambers, valves, walls and the blood vessels (aorta, arteries, veins) attached to your heart. A probe called a transducer is passed over your chest.

Neurocardiogenic syncope: Vasovagal syncope or neurocardiogenic syncope (NCS) is caused by a drop in blood pressure, quickly followed by faster then slower heart rate resulting in poor blood and oxygen flow to the brain which results in temporary loss of consciousness.Neurocardiogenic syncope is also referred to as neurally mediated syncope.

Tilt Table Test: A tilt table test is used to evaluate the cause of unexplained fainting (syncope). For a tilt table test, you begin by lying flat on a table. Straps are put around your body to hold you in place. After about 15 minutes of lying flat, the table is quickly tilted to raise your body to a head-up position — simulating a change in position from lying down to standing up. The table will then remain upright for up to 45 minutes, while your heart rate and blood pressure are monitored. This allows doctors to evaluate your body’s cardiovascular response to the change in position.
